dilution of pigment and
150 times dilution of Vc, and the results of AOSA are
shown in Table 4. We could learn from Table 4 that
the AOSA of the pigment was 3 776.31 U mL-1, 1.24
times of Vc , which proved the pigment extracted from green
wheat bran had a higher activity in active oxygen
scavenging.
